BOX-MAKING MACHINE.

Specification of Letters Patent. Patented NOV. 2'9, 19117..

Application filed August 26, 1914. Serial No. 858,740.

To all whom it may concern:

Be it known that I, JOHN GnLL, a citizen of the United States, residing at Rochester,- in the county of Monroe and State of New York, have invented certain new and useful Improvements in Box-Making Machines, of which the following is a specification.

The object of this invention is to provide a new and improved machine for assembling the sides of interlocking boxes.

Another object of the invention is to make the machine adaptable so as to assemble boxes having sides of different lengths.

Another object of the invention is to provide feeding mechanisms that will select the sides individually and feed them in rapid succession to the machine.

Another object of the invention is to provide a machine with a tapered forming frame along which the sides of the'boxes will be fed and brought together.

Another object of the invention is to form with this forming frame aws, one for each corner of the box which jaws are separately adjustable toward and away from each other.

These and other objects of the invention will be illustrated in the drawings, described in the specification and pointed out in the claims at the end thereof.

In the drawings, a

Fig. 12 is a perspective view of one of the guides showing a modification thereof.

Fig. 13 is a vertical section on the line 13 13 of Fig. 12.

In the drawings like reference numerals indicate like parts.

The machine is built upon bed plates 1 and 2, which are separate from each other. From the bed plate 1 rises the uprights 3 and 1 and from the bed plate 2 rises the uprights 5 and 6. At the top these uprights are united by the yoke 7 from which most of the working parts of the machine are supported. Each of the rods has a shoulder near the top thereof and .the reduced end, the shoulder supporting the yoke 7 and the reduced end passing through the yoke. The reduced ends are threaded so as to. receive the nuts shown at the top of Figs. 1 and 2 by which the yoke is firmly held in place.

The yoke 7 is shown in top plan in Fig. 16 and in bottom plan in Fig. 3 and in sec tion in Figs. 2 and 11. The yoke is made preferably of a single casting having the flanges 8, 9, 10 and 11, the central part of the yoke being filled in by the L shaped web 12 as it appears in plan in Fig. 10. The

yoke has the four lugs or cars, 13, 14, 15 a and 16 thereon through which pass the uprights, 3, 4, 5, and 6.

From this yoke depends four inner jaws 18, 19, 22 and 23, which, together with the outer jaws, 120, 121, 122 and 123 supported in the frame 90, form guides or a forming frame through which the sides of the boxes pass for the purpose of being assembled and making the body of the box.

The support and function of these inner jaws will now be described.

The web 12 is L shaped in cross section as appears in vertical section formed in Fig. 11, the surface 17 fioniing aseat for the jaws 18 and 19' which are mounted thereon, the guide 18 being adjustable and the jaw 19 being fixed. The surface 20 affords a seat for the bed 21 on which the jaws 22 and 23 are adjustably mounted.

As shown in Fig. 3 the jaw 19 is fixed and the aw 18 is adjustable along the slot 2 1 toward and away from the fixed jaw 19;

The bed 21 is adjustable toward and away from the jaws 18 and 19 along the slots 25 and 26 and carries on it the jaws 22 and 23.

The jaw 22 is adjustable on the bed 21 along the slot 27. i The spacing of the jaws 18, 19, 22 and 23 on each other determines the size of the box that will be assembled by the machine and the construction by which this spacing of the parts and the assembling of the boxes is secured will now be described more in detail. 1

It will be noticed that the slots 24, 25 and 26 are provided in th'eyoke and the slot 27 is provided in the bed 21 that is adjustable along the yoke and along the slots 25 and 26.

The bed 21 is substantially as long as the yoke itself, and has at each end thereof lugs 28 and 29 which are threaded to receive the screws 30 and 31, which screws are mounted in suitable hearings in the yoke and project therethrough and are provided withbeveled gears 32 and 33 on their ends.

Fastened to the yoke are the brackets 3 1 and 35 in which is mounted to rotate the shaft 36 on which areprovided the beveled gears 37 and 38 which mesh with the gears 32 and 33 and cause the screws 30 and31 to rotate in unison. See Fig. 3. The screw 31 has a square shank 39 that projects beyond the beveled gear 33 011 which a handle 40, see Fig. 1, may be applied for the purpose of turning the screws. By turning this handle the bed 21 is moved forward and back carrying with it the jaws 22 and 23.

When the bed 21 is suitably placed it is tied to the yoke by means of the bolts 41 and 12, 4:3 and 4 1, which bolts extend through perforations in the ends of the bed. and

through the slots 25 and 26. These bolts are loosened while the adjustment is being made to permit the sliding of the bed 21 and are tightened after the adjustment is finished to hold the bed in its, adjusted position.

Thebed 21 is provided with a screw 45 which engages with the ear 16 on the bracket 56attached to the jaw 22. This screw extends through the ear 17 on the bracket 4-7 provided on the jaw 23 and. carries on its forward end a beveled gear 48 which meshes with the beveled gear 49 carried on the shaft 50 that projects at right angles to the screw 415 throughthe bracket 17. The shaft 50 has a square shank on the end thereof which is engaged bya handle similar tothe handle e0 by which it may be rotated. The j aw does not move longitudinally of the bed 21 means of the bolts 54 and 55 which extend through the slot27 into the bracket 56 which is attached to the jaw 22, see Fig. 10.

The jaw 19 has attached thereto the bracket 57 by which it is rigidly attached to the yoke. This bracket 57 is provided with a lug 58 through which extends the screw 59 on the end of whichis a beveled gear 60, see Figs. 3'and11. Mounted at right angles to the screw 59 is the shaft 62 on which is carried the beveled gear 61 which meshes with the beveled gear 60. The end of the shaft 62 is square so as to receive the handle 51 thereon by which the shaft may be turned so as to rotate the screw 59. f The jaw 18 has the bracket 63 attached thereto by which it is fastened to the yoke, the bolts 6& and 65 being used for this purpose. See Figs. 3 and 10.

From the foregoing it will be understood that by turning the shank 39 the bed 21 will be adjusted forward and back, and by turning the shanks 50 and 52 the jaws 22 and 18 will be adjusted so that any adjustment of thefour jaws may thus be secured for the making of any size box within the limits of the capacity of the machine. j I

The inner jaws 18, 19, 22 and 23 themselves will now be described. 2 i

. Three; of the jaws are shown in perspective in Fig. 5, and all of thejaws are shown in cross section in Figs. 3 and 4;. Each of the jaws is preferably made of a single casting and is adapted to carry two chains which travel thereon. As shown in Fig. at each of the jaws is substantially square incross sec tion. Each of thejaws is channeled to ail ford runways for the two chains. Each of the chains requires two sprocket wheels. The sprocket wheels at thetop are set directly in the casting and the sprocket wheels at the bottom are set in a special bearing block 66 set in the casting at the bottom, see Fig. 2. As shown in Fig. 2 the chains, travel up through the runways at the side of the jaws and down through the runways inthe face oftheaws, the exposed chains in Fig.2 traveling up and the chains exposed in Fig. .5 traveling down. The chains are driven as follows:

The chain 67, see Fig. 5, passes over a sprocket at the top that is mounted on a shaft that is driven by a spiral gear 68. The

70 on which shaft is keyed the spiral gear 71 which meshes witlrthe spiral gear 68 by which the chain 67 is driven. A shaft 7 0 extends through the aw 19' where similar sprockets and spiral gears are provided for the purpose'of driving the chains.

A shaft 7 0 passes through the bearings 7 2 toward the right in Figs. 2 and 3 and carries 76 which meshes with a beveled pinion 77 carried on the transverse shaft 78 which shaft carries a pinion 79 thereon, see Fig. 3. The shaft 7 8 is mounted to rotate in the brackets 47 and 57, in which brackets bearings are provided for the shaft. The bearing in the bracket 47 maintains sliding adjustment with the shaft as the bed 21 is moved forward and back.

Mounted to rotate in the brackets 47 and 56 is the shaft 80 which shaft has the beveled gear 81 on the end thereof meshing with the gear 79. The shaft 80 drives a sprocket wheel and a spiral gear in each of the jaws, the spiral gear on the shaft in each jaw meshing with another spiral gear mounted 011 a short shaft which carries the sprocket wheel. These sprocket wheels in turn drive the chains just as has been above described in connection with the aw 18.

The spiral gear on the shaft in the jaw 19 does not slide thereon while the spiral gear on the shaft 7 0 in the jaw 18 maintains sliding engagement therewith. The spiral gear in the jaw 23 does not slide along the shaft while the spiral gear in the jaw 22 is mounted to slide along the shaft 80.

By means of the gearing just described the eight chains in the four jaws are caused to move in unison. Eachof'the chains carry the dogs 82 by whichtlie boards are forced through the machine. These dogs have a fiat block which makes a liberal bearing contact with the boards as shown in Fig. 5 and it has a pin 86 projecting upwardly therefrom. The grooves or channels in the jaws are cut away at the top to give ample clearance for these blocks as they travel with the chains from one end of the jaws to the other.

The working faces of the jaws taper from top to bottom, as will be seen by inspection of Figs. 2 and 5, it being the object of the chains totake the sides of the boxes with their meeting edges spacedapart as shown at the top of Fig. 5 and draw them down the inclined faces of the jaws and bring their meeting edges together so as to interlock the tongues of one of the parts with the grooves of the adjacent part thus fastening the sides of the boxes together.

It will be seen from inspection of Fig. 5 that the body of the box is formed around the four jaws which jaws terminate at a considerable distance above the bottom of the machine as is shown in Fig. 2 so as to permit the removal of the box body from the jaws after it has been finished. That is after the four sides have been joined together. l

To feed the sides of the boxes and to hold them in contact with the chains and the inner jaws as the sides are advanced by the chains, a series of outer jaws are provided extending parallel to the inner jaws between which two sets of jaws the sides of the boxes pass as they are carried forward by the chains.

This outer set of jaws will now be described.

Mounted on the uprights 3, 4, 5 and 6 is the frame 90 shown in plan in Fig. 4. This frame has lugs at the four corners thereof which are perforated to receive the uprights, to which uprights the frame is clamped by the set screws 91 such as are shown in Figs. 1 and 2. On this frame 90 is the stationary plate 92 on which plate is a stationary bracket 93 and a moving bracket 94, see Fig. 4. The plate 92 has the slot 95 therein to receive the bolts 96 and 97 which fasten the bracket 93 to the plate and receives the bolts 98 and 99 which fasten the bracket 94 to the plate. Mounted to rotate in suitable bearings in the bracket 93 is the screwlOO having the square shank 101 by which it may be turned. This screw has a threaded engagement with the bracket 94 by which the bracket 94 may be adjusted by the turning of the screw. That is, it may be moved toward or away from the bracket 93 along the slot 95.

' lvIOUlltGd to slide on the frame 90 is the with which engages the bolts 106 and 107 which fastens the bracket 103 in place and with which engages the bolts 108 and 109 which fasten the bracket 104 in place, see Fig. 4. Mounted to rotate in the bracket 103 is the screw 110 which has a threaded engagement with the bracket 104 so that on the rotation of the screw the bracket 104 is moved toward and away from the bracket 103.

Mounted to rotate in the stationary plate 92 are the screws 111 and 112, which screws have a threaded engagement with the bed 102, see Fig. 4. Each of the screws carries a sprocket wheel at its forward end which sprocket wheel meshes with the chain 113 by which the one screw is driven from the other so that both rotate in unison. The forward ends of the screws have square shanks so that a handle may be applied to either of them for the purpose of rotating them, see Fig. 1. The bed 90 is provided with the slots 114 and 115 through which slots the bolts 116 and 117 and the bolts 118 and 119 engage for the purpose of clamping the bed. 102 in position or for guiding it when the bed is moved from one position to the other.

Mounted on these brackets are the outer jaws 120, 121, 122 and 123, see Fig. 4, one of which jaws is shown in perspective in Fig. 8. These jaws are all alike and the description of one will suiiice for all of them. These outer aws are shorter than the inner jaws. They terminate at the bottom at about the same point as the inner jaws, but at the top they are shorter because they start below the magazines from which the box members are fed against the inner jaws. The outer jaws serve to uide the box members and hold them against theinner jaws.

The jaw 120 has the inclined working surfaces 124 and 125 along which the boards are fed, which surfaces are exposed at right angles to each other, see Fig. 8. In the corner between these surfaces is the guide 126 which guide is angular in cross section and tapers from top to bottom. This guide is separated from the working surfaces 124 and 125 by the grooves 127 and 128. hen the boards start at the top of the outer jaws the ends of the boards abut against the surfaces of the guide 126. As the box progresses along the jaws, being driven by the dogs 82 on the chain, the edges of'the boxes come together. The tongues on one board are gradually forced into the grooves on the other board until the outer surface of the two boards have come to the common meeting edge after which there is no longer need of the guide 126 and as they pass beyond this point the tongues project beyond each other as is shown at the bottom of Fig. 5 and to give them space into which to project the slots 127 and 128 are provided. These slots could begin where the tongues begin to project beyond each other, but it is more desirable to form the guide in the manner illustrated. I

When the box is finished the tongues wil project beyond each other as is shown in the box at the bottom of Fig. 5. These projecting tongues must be cut off and to cut off the tongues as the boxes are fed along the guides I provide stationary cutting knives on the guides for trimming the boxes which knives will now be described.

On the back of each of the jaws 120, 121, 122 and 123 as illustrated at Fig. 9, are provided the flanges 129 and 130 in which are clamped the sockets 131 and 132, in which sockets are clamped the knives 133 and 134. These sockets are adjustable laterally on the flanges and the knives are adjusted longitudinally in the sockets. These knives project across the grooves 127 and 128 in which the projecting tongues travel and the projecting tongues are trimmed off as the boxes are forced along by the chains.

It will be seen that one outer jaw and one inner jaw are provided for each corner of that corner of the boxand the outer and inner jaws are spaced apart substantially the same as the thickness of the boards which pass between them. Any adjustment that is made in the inner jaws must also be made in the outer jaws to correspond.

,It will be seen that the four outer guides together form the outline of a flat hollow tube or chute, the insideof which has con verging sides and at the corners of the jaws are located the guides 126 which in all the jaws are substantially parallel to each other.

It will also be seen that the outer jaws together make a female form and the inner jaws make a male form and between the two the bodies of the boxes are assembled. 1

Because of the inequality in the thickness of the stock, it frequently happens that the sides do not go together fully, at particular corners, and make tight joints and because of this, it is advisable to provide an extra attachment in the outer jaws for the pur pose of compensating for this inequalityin the stock so as to produce uniformly tight joints in spite of the variations in the stock.

This additional feature is shown in Figs. 12 and 13.

In the working faces such as shown at 124 and 125, is provided a groove or slot 160 in which is pivotally mounted the yielding member 161 pivoted at 162 and pressed outwardly at the bottom. by the spring 163 which is held on a stud 164 by the stem 165. The stud 164 is threaded into the jaw 120 and is adjustable therein and the stem 165 is threaded into the member 161. The stem 165 passes loosely through the stud 164 and is threaded to engage with the nuts 166 and 167. The 'yielding member 161 lies flush with the guide surface 124 at the top there of and is projected out beyond the surface at the bottom by the spring 163 and the spring 163 will be varied in stifiness according to the class of work that is passing through the machine. The setting of the member 161 is determined by the nut 166'which, is screwed up to draw in the member 161 and compress the spring 163 and the nut 166 locked by the nut 167. The initial setting of the member 161 may be varied in or out by the turning of the stud 164.

"To provide for the feeding of the sides of the boxes to the jaws in rapid succession and at regular intervals. I provide the feed,-

ing mechanism that is shown in Figs.1, 2, 5

and 136, supported from adjacent jaws, are shown in Fig. 6, these guides forming a magazine for feeding the sides of the boxes to the machine. These guides have the runways 137 and 138 on which theboards rest and have the upwardly extending flanges which hold the boards laterally in line, the tops of which flanges are beveled or inclined to facilitate the placinglof the boards in the guides. Below the guides are mounted the bars 139 and 140 on which rock and slide the presser feet 141 and 142. Attached to each presser foot is a chain 143 which travels over the forward pulley 144 and then rearward over the pulley 145 and down, having a weight 146 attached to the lower end thereof. The two pulleys are supported by one guide as is shown in Fig. 2. For the purpose of feeding boards to the magazine, a number of boardsare placed in the magazine and either presser foot is rocked to the dotted line position shown in Fig. 6, the handle 147 being used for this purpose. The handle is then drawn back until the presser foot clears the boards that have been added to the magazine and is then moved to the full line position. The presser feet are used alternately in each magazine when additional boards are added to the magazine. 30

s Two weights are pressing the, boards in each magazine forward and against the feed chains in the dogs and as the dogs on the feed chains descend the innermost board is moved downwardly with the chains, allowing the second board. in each magazine to advance and come in contact with the chains so that it in turn will be removed by the next dog following. The inner end of each runway is beveled as shown at 148 in Figs. 2 and 5 to facilitate the removal of the end board, so that it will be started down in the opening between the jaws and the guides.

Pivotally mounted at the top of each of the outer jaws are the dogs 149 which hold the next board in place until it is forced down between the jawsby the dogs on the chains. This dog is held in position by the tension spring 150. As the board is forced down the dog is rocked stretching the spring 150 and as soon as the board has passed the dogs, the dog 149 is returned to its normal position by the spring 150 and as it returns it rides over the dog 82 and the pin 86 on the top thereof until it reaches the stop 151 by which it is held in normal position.

The operation of the machine is as follows:

The tongues or grooves or interlocking joints along the edges of the boards are first dipped into a bath of molten or liquid glue so as tobe coated with the adhesive and a number of them, after beingso treated are put into one of the magazines. The other magazines are filled in the same way and tilt push the boards forward so that the innermost board rests against the inner jaws and in line with the openingbetweenthe inner and outer jaws. The feed'chains take the innermost board from each magazine and start them simultaneously down between the jaws and as they advance in the jaws, the tongues of one board are brought into ongagement with the recesses on the adjacent board and as the advance continues, the tongues of one are forced firmly into the recesses of the other, until the engagement is complete. As the boxes reach the lower part of the jaws, they come into contact with the trimming knives which trim off the surplus material. The feed chains may be arranged to push the boxes past the knives as they may be arranged to leave the last inch or so of the box in engagement with the knives, causing the box to be shoved out by the next succeeding box. In this manner, the body of the boxes with their four corner joints glued and interlocked are assembled ready to receive the top and bottoms which are added later.
